1. a manufacture method for heat exchanger, the method has hollow-fibre membrane layer for manufactureHeat exchanger, this hollow-fibre membrane layer is obtained by mother metal, and this mother metal is led to by having heating mediumMany hollow-fibre membranes of the hollow bulb crossed are constituted, and by by these many hollow-fibre membranesIntegrate and global shape is formed as the shape of cylinder,The manufacture method of this heat exchanger is characterised by, including:

  • Rolling step, by described each hollow-fibre membrane respectively along described cylinder axial aroundThe axis described cylinder is wound, thus obtains described mother metal,In described rolling step, by described each hollow-fibre membrane respectively from described cylinderAxial side towards opposite side and turn back at this opposite side and turn again to described sideA round period, by this hollow-fibre membrane around described cylinder one enclose above andIt is wound in described cylinder less than in the range of two circles.
